The Springfield 1911 Ronin AOS pistol in .45 ACP with a blued slide and satin aluminum frame (brand part no. PX9118LAOS) blends classic 1911 design with modern Agency Optic System compatibility, accepting optic plates that fit popular footprints like RMR, Shield, Delta Point Pro, and Docter. Springfield Armory builds the pistol with a 4.25-inch forged stainless steel match-grade barrel on a fully supported ramp, and a forged aluminum alloy frame keeps the weight around 29.5 ounces for easy carry. Each optic plate includes an integral rear sight for proper optic height and visible co-witnessing, and a fiber optic front sight rounds out the sighting system. Crossed cannon wood laminate grips and a Commander-length GI-style recoil system complete the classic-modern build. Among optics-ready 1911-pattern semi-auto handguns, this Ronin AOS configuration favors shooters who want red dot compatibility on a traditional 1911.
